Cardio-Oncology is an emerging interdisciplinary field focused on the cardiovascular care of cancer patients and survivors. It addresses the prevention, diagnosis, and management of heart-related complications arising from cancer therapies such as chemotherapy, radiotherapy, targeted agents, and immunotherapies. Conditions commonly encountered include cardiomyopathy, heart failure, arrhythmias, hypertension, thrombosis, and vascular injury. Cardio-oncology emphasizes early risk assessment, cardiac monitoring during treatment, and long-term surveillance to mitigate cardiovascular toxicity without compromising cancer care. Collaboration between cardiologists, oncologists, and primary care providers is essential to ensure comprehensive, patient-centered management. Research is advancing the understanding of molecular mechanisms behind cardiotoxicity, as well as the development of cardio-protective strategies and tailored treatment plans. As cancer survivorship grows, cardio-oncology plays a vital role in improving both cardiac and overall outcomes.
